Comment 3 for bug 1028526

4.2.4-1ubuntu1 dropped the Ubuntu delta for dropping privileges so we could use the upstream code instead. The order of when upstream open the leases file must be different than the previous patch because the lease files need to be owned by root:root, not dhcpd:dhcpd. While add 'capability dac_override' to the profile would fix the issue, it would be better to update the upstart job to adjust the permissions on the lease files so we don't need the expanded permission. I am preparing an upload for this now.
